A leaflet seems kind of spammy... I'd probably trash it if I got one in my hands. Sure, if you send out a thousand you're bound to get a response.
Try sending out something tangible to really catch someone's eye. Check out Neil's self-promotion from a few years back. Send out a dozen of those and you'll leave a memorable impression. Hell, I didn't even get one of the cans and I still remember it 2 years after seeing it!
It doesn't have to be that far-fetched though. Have a go at making a pop-out card that features your work (I'm sure you can do something with that volkswagen there)
Using a bean can is Genius, plus considering how cheep you can pick a can up for these days.
Problem for me is I have been given a list of direct contacts to approach......mailing out 100 cans of beans might just get the bomb squad dragging me out of bed at 6am.
